A story description task was used to elicit short stories by 10 Italian children and adolescents with Down's syndrome and 10 normal children matched on mean length of utterance (MLU). Data analysis focused on a subset of lexical, morphological and syntactic aspects of language use. The results show that the subjects with Down's syndrome and their normal matches use a similar lexical repertoire. However, the two groups differ with respect to omissions of free morphemes, and some aspects of syntactic and pragmatic abilities. These data on Italian subjects corroborate and extend previous findings on other languages: despite an extensive repertoire of lexical and grammatical items, subjects with Down's syndrome seem unable to use such elements appropriately and consistently across contexts.
一项故事描述任务被用于让10名患有唐氏综合征的意大利儿童和青少年以及10名在平均语句长度（MLU）上匹配的正常儿童创作短篇小说。数据分析聚焦于语言使用中词汇、形态和句法方面的一个子集。结果表明，患有唐氏综合征的受试者及其正常匹配对象使用的词汇库相似。然而，两组在自由语素的省略以及句法和语用能力的某些方面存在差异。这些关于意大利受试者的数据证实并扩展了先前对其他语言的研究结果：尽管拥有大量的词汇和语法项目，但患有唐氏综合征的受试者似乎无法在不同语境中适当地、一致地使用这些元素。
